dot1qStaticMulticastForbiddenEgressPorts
Module: Q-BRIDGE-MIB
OID (symbolic): Q-BRIDGE-MIB::dot1qStaticMulticastForbiddenEgressPorts
OID (numeric): 1.3.6.1.2.1.17.7.1.3.2.1.4
Node type: OBJECT-TYPE
Type: PortList
Access: read-write
Description: The set of ports to which frames received from a specific port and destined for a specific Multicast or Broadcast MAC address must not be forwarded, regardless of any dynamic information, e.g., from GMRP. A port may not be added in this set if it is already a member of the set of ports in dot1qStaticMulticastStaticEgressPorts. The default value of this object is a string of zeros of appropriate length.
The value of this object MUST be retained across reinitializations of the management system.
What is dot1qStaticMulticastForbiddenEgressPorts?
This object holds a byte string representing which switch ports should never receive multicast or broadcast traffic from a specific source and destination address. Network engineers use this to block unwanted broadcast storms and multicast flooding on certain ports, improving network stability. For example, you might block port 5 from receiving broadcasts from port 1 to prevent redundant traffic on devices that don't need it.
